XY P2

• Pin 1 (XY P1.21) is upper left when looking into connector with key up
• Keeps P2 and P1 number sequential
• Matches 1 to square key via on adapter PCB

This is used on the Z and X axis. Taken from Z axis assuming X is the same

BBB P8:

• Pin 1 is next to the ethernet port
• Pin 1, 2 are ground
• Is the one without the JTAG port next to it

The signal applied to the optocoupler reference will
determine the sinking/ or sourcing configuration of the
inputs. To set the inputs for sinking operation, a +5 to +24
VDC supply is connected. If sourcing, the reference is
connected to ground

Motor/driver:

• Logic Threshold (Logic 0): < 0.8 VDC
• Logic Threshold (Logic 1): > 2.2 VDC

BBB: While the GPIO pins on the BeagleBone Black run at 3.3 Volts, …

Sounds like should be able to directly hook BBB output to MDrive17+. Revisit if there are any signals that need to go vice versa

Select the example configuration that matches your hardware (I suggest starting with the CRAMPS configuration if you don't have any hardware) and launch LinuxCNC

NOTE: If you want to switch between configurations that load unique hardware overlays, you should reboot

CRAMPS board schematic

From reading schematic, default/intended pinout is:

I'm not sure if these are available for purchase (or even if I need it), but it has example configs and documentation

Reading through the user guide

Hmm this is unfortunate:

Each BeBoPr++ comes with a license for use of the PRUSS stepper driver firmware. This
stepper driver is proprietary code that runs on a PRU co-processor and is stored in the
BeBoPr++'s on-board EEPROM. The driver handles deterministic and accurate timing of the
stepper pulses for all four axes simultaneously. It also generates the acceleration and
deceleration ramps. Via the API†, custom applications can easily generate accurate stepper

Does this mean the PRU's are usually unusable?

Probably not looks like there's also an open source version:

An open source code repository to build a 3D printer with the BeBoPr++ is available at
https://github.com/modmaker/BeBoPr. This code uses one of the PRU coprocessors for the
step pulse generation and can freely be changed.

Looks like LinuxCNC should have reasonable support out of the box

It has support for the BeBoPr since the original (first) BeBoPr and all software, including the
PRU stepper code is open source. As a community effort, it evolves faster than the BeBoPr 3D
printer code

Not worth the effort to figure out how it works. Replace with beaglebone black

PanaVise PCB holder (already had it around)

As centered won't be able to scan whole PCB. Need to find a way to re-mount it

Need to drill new hole on side to use the entire scan area

Allows adjusting PCB angle

Need to mount mast to t-slot

Instead of using the mast put stand offs on both ends onto t-slot. Maybe make an aluminum adapter if I need something more solid
